By the early 1990s, Heavy Metal Parking Lot had become an underground cult-classic, usually traded on bootlegVHS videotapes. It was reportedly a favorite on the Nirvanatour bus, among many other bands. Due to growing popularity of the film, music copyright issues arose between the producers and Judas Priest, though they were eventually resolved. The film has been referred to as the "Citizen Kane" of Wasted Teenage Metal.
Sequels
Krulik and Heyn attempted to follow upHeavy Metal Parking Lot with Monster Truck Parking Lot in 1988, which showed fans of a monster truck rally, but the film was unfinished and unreleased. They then created Neil Diamond Parking Lot which showed fans before a Neil Diamond concert at the same Capital Centre parking lot, ten years after the original. In 1999, they created Harry Potter Parking Lot. Krulik and Heyn created and co-produced the 2004 TV seriesParking Lot in association with Radical Media, which was broadcast on Trio. The series showed enthusiasts of various bands and activities. Eight episodes were produced. In 2006, a sequel of sorts was released by SnagFilms, entitled Heavy Metal Parking Lot Alumni: Where Are They Now. The 19-minute film looks at the adult lives of several of the young people featured in the original 1986 film.
In May 2006, the documentary was finally released on DVD, to coincide with the 20th anniversary of its filming. The DVD version contains the original 17-minute film, as well as 2 hours of bonus features that were left out of the original version and finally an interview with the infamous "Zebra-man", whom Krulik and Heyn tracked down and interviewed in the summer of 1999, 13 years after the original filming.
